Int. Cl. B65d 75/06, 65/04 US. Cl. 229-87.2 3 Claims ABSTRACT OF THE DISCLOSURE A compact package of coins wrapped in a heat shrunk film material formed from a roll of heat shrinkable film material and having transverse end seals and a horizontal seam.

This application is a continuation-in-part of my application, Ser. No. 643,257, filed June 2, 1967, now abandoned.

This invention relates generally to the wrapping of a pre-selected number of coins in a package to facilitate handling and more particularly to the wrapping of a preselected number of coins in a heat shrunk film material package.

Prior to this invention coins have been wrapped in preformed tubes which after the insertion of the coins has to be, in most instances, manually closed to retain the coins in the container. Furthermore, in financial institutions, where a large number of coins have to be wrapped to handle every day transactions it is necessary to inventory large amounts of pro-formed tubes resulting in the loss of a lot of area which could be utilized for a more profitable operation. Also, the method of manual handling coins is slow and laborious since an operator must pick up each of the tubes, place a counted number of coins in the tube and then move the tube to another station to crimp the end of the tube over the coins.

Therefore, it is an object of the invention to provide a new and novel Wrapped coin package.

Another object of the invention is to provide a package of a pre-selected number of coins wrapped compactly in a heat shrunk film material.

A third object of the invention is to provide a package of a pre-selected number of coins wrapped compactly in a heat shrunk film material pillow package.

Other objects and advantages will be clearly apparent as the specification proceeds to describe the invention with reference to the accompanying drawings in which:

FIGURE 1 is a perspective view of the novel wrapped package prior to heat shrinking of the package, and

FIGURE 2 is a perspective view of the completed novel wrapped package of coins.

FIGURE 1 shows the coins wrapped in a heat shrinkable thermoplastic film material. Numerous heat shrinkable thermoplastic films are commercially available which can be employed to provide the wrapping around the coins 12. Examples of thermoplastic heat shrinkable materials suitable for the purpose are S.T. Vitafilm made by Goodyear Tire and Rubber Company; Polypropolin, a product of Dow Chemical; Cry-O-Vac, a product of W. R. Grace 00.; and Reynolon, which is made and sold by Reynolds Aluminum Company.

Patented May 20, 1969 Looking now to FIGURE 1, a pre-selected number of coins 12 to be wrapped are enclosed in a bag of heat shrinkable thermoplastic film material 10. The bag 10 is defined by a transverse heat seal 14 at both ends substantially parallel with one another and a longitudinal heat seal 16 extending from transverse heat seal 14 to transverse seal 14 to enclose the coins 12.

FIGURE 2 shows the package of FIGURE 1 after it has been subjected to a heat treatment in a shrink oven at appropriate temperature. The film material 10 has been shrunk around the coins 12 to form a compact wrapping. Preferably, the transverse seal shrinks to a size which is equal to or shorter in diameter than the diameter of the coin being packaged thereby pulling the longitudinal seal 16 around the edge of the end coins in the package to provide a tight fit. Depending on the film material and the size of initial package the shrunk transverse seal can be longer or shorter but should not be any longer than the diameter of the coins being packaged.

Most commercially available film material 10 is transparent and/or translucent which is advantageous since the ultimate consumer can verify the count of coins in the package without breaking open the package. The package or film material 10 can be suitably printed on to show the number of coins therein and/or the institution from which it came. Other suitable information can, of course, be printed thereon.

The herein disclosed wrapped coin package is compact, strong and can be readily transported. Furthermore, the use of shrink film provides a package which can be transparent so that the customer can check the number of coins therein without destroying the outer wrapping.

Although I have described in detail the preferred embodiment of my invention, I contemplate that many changes may be made without departing from the scope or spirit of the invention and I desire to be limited only by the claims.

That which is claimed is:

1. A package of wrapped coins comprising: a sealed bag of heat shrunk thermoplastic film material, a plurality of coins in said bag, said bag having a first transverse heat seal at one end and a second transverse heat seal at the other end substantially parallel to said first heat seal, said first and said second transverse seals having a length no greater than the diameter of said coins, and a longitudinal seal integral with said bag extending from said first seal to said second seal and being integrally connected thereto.

2. The structure of claim 1 wherein said first and second seals are shorter in length than the diameter of said coins.

3. The structure of claim 1 wherein said film material is transparent.
